I saw this movie on tv when I was a kid, it was in color and looked like it was released in the early to mid 70s. It involved a homely girl looking for love, but she kept going out with guys who were just looking to score. She ends up moving in to an apartment building and meets an artist/sculptor? who lives in one of the other apartments and they argue at first but fall in love later on. I seem to remember the guy looked like Treat Williams, but I can’t find this title in his filmography. The girl I think was a redhead, that’s all I remember.
